Title: Circular membrane spring for vehicle transmission clutch - has internal radial tongues for preloading operating sleeve
Inventor: KRALL ADALBERT ING GRAD
IPC: F16D13/58
Filed: 1975-09-05
Abstract: A vehicle transmission clutch has a membrane spring plate (7) with internal radial slots. the outside edge of the membrane spring produces an axial force against the friction plate pressure ring (6). Some of the internal radial tongues (26) are in contact with the axially sliding clutch operting sleeve (22). The axial force produced by the membrane tongues (26) ensures that the clutch operating sleeve (22) is preloaded at all times. It is therefore not necessary to include a separate clutch return spring that acts on the operating sleeve. Since the axial loading of the operating sleeve (22) forces the sleeve to rotate with the clutch, its bearing life is substantially increased.

Title: Liquid droplets separation from gas stream - using corrugated plates with catchment traps followed by smaller corrugations
Inventor: REGEHR ULRICH DR ING
IPC: B01D53/26
Filed: 1975-11-27
Abstract: System consists of a series of corrugated plates arranged parallel to each other in the direction of flow. These have catchment ribs along the peaks of the corrugations. After the large corrugations, in the direction of flow there are located a series of smaller undulations, the peaks and troughs of which are perpendicular to the line of flow. The undulation zone can be superimposed or joined to a part of the plate which is parallel to the flow direction. Several such zones can be included as part of the plate alternating with catchment traps. The use of a corrugated plate separator is well established. However they tend to suffer from carryover at high gas velocities and liq. loadings. The separator describes considerably extends the range of such units without carryover or re-entrainment.

Title: Determining quantitatively two different fissile materials in sample - esp. in spherical fuel element using preliminary calibration with varying absorber
Inventor: DAOUD HASSAN DIPL PHYS
IPC: G21C17/06
Filed: 1976-05-14
Abstract: Determining the proportions of two differing fissile materials in a specimen, where the two materials have differing ratios of fission to absorption (fissile material to absorber material), consists of continuously moving the specimen along a path (call channel) in a critical reactor. At different positions along the channel the specimen causes position-dependent disturbances to the reactivity which can be calculated from the consequent change in measured power (neutron flux change with time). Initially, the dependence of the ratio of the specimen influencing functions for the two fissile materials upon the neutron spectrum existing at one position of measurement is determined and is used, in conjunction with a calibration measurement, to determine the change in the ratio of the two specimen influencing functions with the neutron spectrum at this position of measurement; then, a specimen requiring investigation is conducted through the central channel of the core and its specimen influencing function is determined at various positions of measurement having differing neutron spectrums; from this specimen influencing function, the proportions of the two types of fissile material is determined by the values obtd. from the calibration measurement. Used in particular for analysing the proportions of materials in spherical nuclear elements contg. fissile and absorber material and moderator, and more specifically, for determining the proportions of U-235 and U-233 in a fuel element.
